SAFETY. DURABILITY. ECONOMY.
For the ii
Tread, we issue this special
when the merits of that device are known its use will
become well-nigh universal. During the two years since
its introduction in this country it has rapidly gained in
favor as a building accessory, and as a means of repairing
the stairways of old buildings, the smooth borders of side-
walk lights, inclined passages, etc., giving a secure foothold
wherever used. It enables the builder to provide a per-
manently safe stairway, as the Safety Tread will not wear
hollow or shelving like wood, slate, or marble, and while
having the durability of steel
Will Not Become Slippery Like Iron.
We confidently assert that an iron stairway covered with
Mason Safety Tread in the manner customary among
the best architects, is the most durable, the safest, and the
most economical form of stair construction for a mercantile
or office building, factory or warehouse, school house or
other public building. We are prepared to maintain this
not only by reason but by experience, and to support it
by the endorsement of a goodly number of architects
whose names will be at once recognized as among the
most eminent in the profession.
In Boston, the headquarters of- the American Mason
Safety Tread Co., this protective device has proved so
acceptable that not only are hundreds of stores and mer-
cantile buildings provided with it upon stairs and sidewalk
lights, but a large majority of the buildings now in pro-
cess of erection or designing have Mason Tread specified
by the architects, who recognize the advantage of its use.
■■! THE MAsOX SAFETY TREAD.
How it is Applied to Stairs.
The usual method of application is to have the iroi
treads cast with a rebate or sinkage extending to withil
three inches of either end, and from six to ten inches frort
the extreme front edge toward the riser. In this sinkagi
the Safety Tread is firmly attached with
a level surface for the entire -:
the V grooves, in which all dust or dirt settles and I
easily swept out. The portion of the tread not coverec
with our material may be quadrilled or grooved accordinj
to the taste of the architect. The use of the Safetj
Tread with nosing to lap over the edge is optional. Wc
recommend in most cases the six-inch width withoul
Progressive architects have heretofore been largely pre-
cluded from the use of iron stairs by the fact that the
treads soon become polished by wear, and are extremely
dangerous. Marble and slate have been used as substi-
tutes where a fireproof substance is required, but in addi-
tion to the danger of slipping on these materials it is well
known that they become hollowed and shelving to such an
extent that they are unfit for use in a few vears in a busy
place. The Mason Tread overcomes this difficulty, as
It Does Away with all Objection to the Use of Iron,
and enables the construct
stairway of the greatest c
protective appliance known.
The Mason Safety Tread consists of a base of hard
rolled steel, from which rise ribs forming dovetail grooves
at intervals of about one-quarter of an inch. This quarter-
inch space contains a V groove extending half way to the
bottom of the metal. The dovetail grooves are filled with
lead solidly rolled in and firmly held. The great durability
of the Safety Tread is due to the firmness of the steel ribs,
which take the wear; its quality ol safel

Why We Call it " Unwearable."
To prove the extreme durability of the M
Tread we need only mention one notable instance among
I of the Brooklyn
Bridge, who made their first trial of the M
Tread over two years ago, soon adopted it for all the
stairways of that great structure, and now use no other
covering. This furnishes the severest test possible to be
given, as these stairs are constantly in use, and official
week, and the treads are still in good condition.
With such an object lesson as this before us, we can
declare with confidence that when subjected to ordinary
conditions of travel, Mason Safety Tread upon a stair-
way will outlast the building in which it is used. The use

THE MASON SAFETY TREAD.
The use of the Mason Safety Tread is especially
desirable in buildings for school purposes, where the wear
upon the stair trc.uk is so constant. Those familiar with
the condition of the school houses in our larger cities
know that in n lirs are, if of iron, worn
to a dangerous polish; if of wood, marble or slate, worn
in hollows far below the original surface and shelving
at the edge. The Mason Safety Tread has been used in
many places for repairs on such stairs, and architects are
now placing it in many new buildings. This use of the
Safety Tread has been cordially approved by Prof. Francis
W. Chandler, head of the Department of An
the Massachusetts Institute of Technology, and, as Con.
suiting Architect for the City of Boston, for the several
new school houses now building for the city. We are
pleased to be able to refer also to the reports of public
officials contained in our catalogue, for other endorsements
of this use of our product.

1-2 THE MASON SAFETY TREAD.
Under this head we mention a few from the very large
number of buildings where the Mason Safety Tread has
been used lo protect stairways of wood, slate, marble, and
iron. It is the only material with which satisfactory and
durable repairs can be made upon worn stairways. We
have never made a business of seeking testimonials, but
we are able to refer to the reports of public officials
expressing their entire satisfaction with the Safety Tread ;
to the fact that the agents or trustees of many of the
largest estates in Boston use it liberally in the protection
of the property under their care ; and to the fact that in
a very large number of instances where the material has
been used in stores, repeated orders have been received.
We invite inspection of our work at any of the following
City Hall, Boston. Large platform ( loo square feet)
covered, and eleven wide flights of iron stairs, covered to
a width of 9 1-2 inches. These stairs were fluted or
ribbed, but had become so smooth by wear that many
accidents occurred, and several people received serious
injuries. Since the repairs no trouble has been experienced
from slipping. The work was done by order of Mayor
Faneuil Hall and Quincy Markets, Boston. The granite
steps and entrances to these buildings are covered with
Mason Safety Tread, which not only protects the sur-
faces from further wear, but prevents slipping in places
formerly very dangerous. Heavj boxes and
barrels are dropped from step to step without injury to the
tread, and its non-slipping quality is retained even when
covered with grease. ( George E. McKay, superintendent.)

of frequent accidents cause.! by the smoothness of the re-

in the past two years, showing that they are abundantly
pleased with our work.

MASON SAFETY LIGHT.
We have devised a Safety Light with protected borders
for covering Sidewalk Vaults. The frame is exceedingly
strong, and its borders and intermediate bars are protected
with strands of lead to render them non-slipping. We
are thus enabled to make the percentage of glass surface
very large, and concentrate a large amount of light in the
space beneath. This method dispenses with all knobs or
pegs, and gives a perfectly safe, level surface, which will
prove extremely durable.
Those who prefer can have the usual forms of sidewalk
light frames cast with a sinkage in the border, in which to
place the ordinary steel strips of Safety Tread. Nar-
rower strips may be embedded in the cement to pro-
